[Patch, fortran] PR fortran/100948 - [12 Regression] ICE in gfc_conv_expr_val, at fortran/trans-expr.c:9069

[José Rui Faustino de Sousa]

Hi all!

Proposed partial patch to:

Bug 100948 - [12 Regression] ICE in gfc_conv_expr_val, at 
fortran/trans-expr.c:9069

Patch tested only on x86_64-pc-linux-gnu.

Reuse previously calculated full string length to set string section 
default upper bound.

This patch only fixes the ICE the code produced is still wrong.

Thank you very much.

Best regards,
José Rui
