I can obtain the same effect by substituting the sprintf call with a
call to pow or exp.

I already put up a test case with two threads doing some floating-point
calculation in loop, but could not reproduce the error.

I'll try to investigate with different settings for the microblaze
processor.

My current hardware configuration is as follows:

BEGIN microblaze
 PARAMETER INSTANCE = microblaze_0
 PARAMETER HW_VER = 6.00.b
 PARAMETER C_USE_FPU = 1
 PARAMETER C_DEBUG_ENABLED = 1
 PARAMETER C_NUMBER_OF_PC_BRK = 2
 PARAMETER C_PVR = 2
 PARAMETER C_ICACHE_BASEADDR = 0x44000000
 PARAMETER C_ICACHE_HIGHADDR = 0x47ffffff
 PARAMETER C_DCACHE_BASEADDR = 0x44000000
 PARAMETER C_DCACHE_HIGHADDR = 0x47ffffff
 PARAMETER C_FSL_LINKS = 1
 PARAMETER C_USE_BARREL = 1
 PARAMETER C_USE_DIV = 1
 PARAMETER C_FAMILY = spartan3e
 PARAMETER C_INSTANCE = microblaze_0
 PARAMETER C_USE_ICACHE = 1
 PARAMETER C_USE_DCACHE = 1
 PARAMETER C_NUMBER_OF_RD_ADDR_BRK = 0
 PARAMETER C_NUMBER_OF_WR_ADDR_BRK = 0
 BUS_INTERFACE IOPB = mb_opb
 BUS_INTERFACE IXCL = ixcl
 BUS_INTERFACE DXCL = dxcl
 BUS_INTERFACE SFSL0 = download_link
 BUS_INTERFACE DOPB = mb_opb
 BUS_INTERFACE DLMB = dlmb
 BUS_INTERFACE ILMB = ilmb
 PORT CLK = sys_clk_s
 PORT DBG_CAPTURE = DBG_CAPTURE_s
 PORT DBG_CLK = DBG_CLK_s
 PORT DBG_REG_EN = DBG_REG_EN_s
 PORT DBG_TDI = DBG_TDI_s
 PORT DBG_TDO = DBG_TDO_s
 PORT DBG_UPDATE = DBG_UPDATE_s
 PORT Interrupt = Interrupt
END
